a) (f+g)(x)=6x^3-x^2+3x+4+8x^3-1

=14x^3-x^2+3x+3

b)(f+g)(2)=14(2)^2-4+6+3

=61

c)(f-g)(x)

=6x^3-x^2+3x+4-8x^3+1

= -2x^3-x^2+3x+5

d( (f-g)(-3)

= -2(-3)^3-(3)^2+9+5

=59

Answer:

f^{-1}(x)=25(x-2)^2

Step-by-step explanation:

The inverse function can be found by solving ...

  f(y) = x

  (√y)/5 +2 = x

  (√y)/5 = x -2 . . . . . subtract 2

  √y = 5(x -2) . . . . . . multiply by 5

  y = 25(x -2)² . . . . . square both sides

The inverse function is ...

  f^{-1}(x)=25(x-2)^2

_____

<em>About the graph</em>

How many solutions does 2.3y+3.2-y=2.1+1.3y+1.1 have?
jeka57 [31]
1.3y +3.2 = 1.3y +3.2

we notice that both sides of the equation are identical. So substitute y with any value and the equation would still be correct.

y has infinite solutions.
